I think the prolific Charles has already mentioned this article by Ramesh Ponnuru, who claims Rudy’s candidacy should be torpedoed because of abortion. He says he was particularly bothered by his support of partial birth abortion:
This year, Giuliani’s position changed. He said that he now supported a ban because it included an exception for the life of the mother. This explanation made no sense. He had never previously mentioned this concern, and earlier versions of the bill that he opposed had included a life-of-the-mother exception. But Giuliani’s nearly pointless dishonesty was not as troubling as the mere fact that he had once supported partial-birth abortion at all.
Read the whole thing here to see why Republicans should not “let bygones be bygones.”
